[rtl] rtl pthread bug ?? (was unwelcome reboot)

[Olaf Petzold]

Hello,

the attached code crashs, why ? The goal was to synchronize two rtl threads
with kernel-2.2.14-rtl-2.2. The counter mechanism is working as we can see on
the debug messages. After the screen was full of those messages, the box was
rebooting. It's not clear for us why it's does. The source isn't using the
periodic mode. If I see these problems, I guess that the problems from the
thread "unwelcome reboot" does not regards to comedi. The only thing: inside
the callback function there should not be a rtl_printf - thats kills the
interrupt handler! Mostly the cursor disappears after insmod this module.

Who can help ??

Thanks  Olaf
